Product details

This is a 70 V, 70 mA Schottky diode in the SOT-323 (SC-70) surface-mount package. The 70 V reverse voltage rating covers low-voltage rail protection and clamping in 3.3 V to 24 V systems. The 70 mA average rectified current is typical for signal-level steering, OR-ing, and ESD clamp applications — not for power rectification. Forward voltage drops 1 V maximum at 15 mA, and the junction capacitance is 2 pF at 0 V, 1 MHz, which keeps switching loss low in high-frequency signal paths.

SOT-323 footprint and handling note

The BAS70WFILM uses the SOT-323 (SC-70) three-lead package. It is a surface-mount device — no through-hole option.
